Be it known that-I, WALTER F. PREssLER,

citizen of the United States of America,

storage tank, commonly used in connection with windmills, reaches apredetermined height, the wind wheel of the motor will be automaticallystopped and consequently the inflow of water into the storage tankstopped; Also as a predetermined amount of water in the storage tank isconsumedthewin'd wheel will be automatically released and allowed torevolve, thereby again pumping-water into the storage tank, theseactions of 'stopping and starting being rel peated and consequentlypreventing the overflow of the storage tank.

A further object is to automatically stop and start the wind wheel andconsequently the pumping action of the motor, by means of a verticallyguidedreceptacle, having a valve therein, said valve being connected toand controlled by a float in the storage tank, said verticallyguidedreceptacle being also connected by means of a wire to the tail or rudderof the wind-wheel so that upon a downward movement of said receptacle,the rudder will be swung against the action of springs and at the sametime apply the brake to said wind-wheel.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

FigrL-is a sectional view ofFig. 2. i

Fig. 5 is a perspectivev View of the. vertically movable receptacle; 7 V7 Referring to the drawings 1 designates a conventional form of windmilltower,

on line l4t j upon the upper end 2 of which aconventional form of windmotor 3 is mounted. The

motor-3 is provided. with a conventional wind-wheel 4 adapted to berotated by the action of the wind. The motor 3 is also provided with arudder 5, normally held at right angles to the wind wheel by means ofsprings 6,-however as the rudder is swung out of right angled position-to the wind wheel, against the action of either of the springs 6, abrake 7 will be actuated, which will stop themotor and consequently thepumping of water; the purpose of stopping the motor will presentlyappear. The water as itis pumped is conveyed into the storage "tank 8,by meansof the pipe 9, said storage tank being mounted upon a tower, 10,at such a height that the'upper end of said tank 8, will be higherthanthe discharge end 11 of the overflow'pipe 12, which is connected at 13to the tank 8. The. discharge end 1101: the overflow pipe 12- .is,disposed over a vertically movable receptacle 14:, which in turn isloosely mounted in the yoke 15. The yoke 15 comprises the annular ring16 having depending guide arms 17 adapted to be engaged by the guidelugs 18, upon the receptacle 14:, so that said receptacle will beprevented from rotation.

The ring 16 of the yoke 15 is provided with an arm 19, having anelongated slot 20 registering with an elongated slot 21 in the arm 22 ofthe vertically slidable collar 23, which is adapted to be vertically andlaterally adjusted on the tower, by means of the set screw 24. Radialadjustment of the yoke 15 may be accomplished by means of the bolts 25.The arm 19 is provided with a vertically and laterally extending arm 26and mounted upon the pin or bolt 27 in said arm is a pulley 28.

The bottom of the receptacle 14: is provided with a centrally locatedport 29. Hinged at 30 and adapted to seat upon and normally close saidport is a valve 31. Connected at 32, to said valve 31 is a wire or chain33, which extends upwardly and over the pulley 28, thence over a pulley3% carried by the bracket 35 which is mounted upon the top of the supplytank 8. The wire or chain then extends downwardly and is connected at36, to the float 37,111 the supply of said water and receptacle 1%,.willovercome the tension of one of the springs 6.

and swing the rudder 5 to one side, thereby operating the brake 7 andstopping the motor. As the water aim the tank 8 is consumed, the float37 will fall until the slack in the wire or chain 33 is taken up, thevalve 31 will be opened and the water lnathe ree ceptacle allowed toescape, thereby allowing normal position with the wind wheel l andconsequently releasing the brake 7, the tension of the springs 6 beingstrong enough. to raise and support the receptacle 1& when;

empty.

The submersion of the float can be-regulated by means of the weights l5and the amount of slack in the wire or chain 33 may be regulated asdesired.

It will-be noted that as the rudder 5 is swung from one position to theother and is suddenly stopped, by the stops Q6 and 417,

that the momentum of the bUCkQtwOIl the sudden stop of the rudder, willcause considerable strain upon the wire 42 and often break the same. Toobviate this a resilient connection 48 is provided on the wire 42, whichconsists of a casing i9, having a piston and piston rod 50 mountedtherein. A spring 51 is interposed between the piston and the bottom ofthe casing, thereby providing a yieldable member to take up the suddenshock incident to the sudden stopping of the rudder in its twopositions.

The invention having been set forth what is claimed as new and useful isIn combination with a wind mill, a pump operated by the windmill and atank supplied by the pump, a float in the tank connected to a normallyclosed valve in a vertically movable weight vessel, saidv weight vesselbeing connected to the controlling elementof the wind mill and heldraised thereby when the wind, mill is in operation, an overflow vpipeleading from the tank and arranged to discharge into the weight vessel,means to opensthe valve of the weight vessel when the weight vessel isin a lowered the rudder to swing voutwardly and into its position, anadjustable yoke guiding ,means surroundingjthe weight vessel and havingdepending arms. preventing binding of the weight vessel during itsupward and downward movement, means at diametrically pposite sides ofsaidweight vessel to engage said depending arms. thereby preventing r0-tation of theweight vessel and means whereby the yoke, member may belaterally adj usted, extended and secured in its adjusted position.
